base with trimethoxy group on benzothiazole moiety, 4y was the best. This was followed by the synthesis of a series of the designed molecules by a convenient synthetic route and evaluation of their anticancer potential. Most of the compounds have shown significant growth inhibition against the tested cell lines and the compound 4y exhibited good antiproliferative activity with a GI50 value of 3.8µM specifically

The 1,2,3-triazole ring fused with pyridine/pyrimidine was explored as new template for the identification of potential antimicrobial agents. The regioselective synthesis of these pre-designed N-heteroarenes was achieved via exploring the application of Buchwald’s strategy (i.e. C–N bond formation/reduction/diazotization/cyclization sequence) to the N-heteroarene system. Two of them showed promising
A series of 2-anilinopyridine dimers have been synthesized and evaluated for their anticancer potential. Most of the compounds have showed significant growth inhibition of the cell lines tested and compound 4d was most effective amongst the series displaying a GI(50) of 0.99 mu M specifically against the prostate cancer cell line (DU145). Studies to understand the mechanism of action of 4d indicates that it disrupts microtubule dynamics by inhibiting tubulin polymerization thereby arresting the cell cycle in G2/M phase. Competitive colchicine binding assay suggests that 4d binds into colchicine binding site of the tubulin. Further from some detailed biological studies like mitochondrial membrane potential, caspase-3 assay, DNA fragmentation analysis and Annexin V-FITC assay it is evident that 4d induces apoptosis. Molecular modeling studies provide an insight into the binding modes of 4d with colchicine binding site of tubulin and the data obtained correlates with the antiproliferative activity.

Deep eutectic solvent (DES)/lipase catalyzed efficient synthesis of N-aryl amines from electron deficient aryl chlorides and amines at ambient temperature is reported. Its significant features include excellent yields of products, use of biodegradable, non-toxic and recyclable catalysts, thereby avoiding toxic metal catalyst/solvents making these protocols environmentally benign.
